    Our Awards and Recognition

    Is 4IRE a freelance platform like Upwork?

    4IRE is not a freelancer platform; we’re an agency with a large in-house and distributed team of coders with a completely different principle of staff recruitment. All developers getting to the team are screened for competency and undergo a series of exams to prove their hands-on expertise in Solidity programming. This selection process concerns both in-house and remote developers, ensuring that 4IRE clients always get top-notch service.

    Can I hire a solidity engineer within 24 hours with 4IRE?

    Yes, the 4IRE procedure of developer recruitment allows for such a speedy hiring pipeline, closing the recruitment task within 24-48 hours after you turn to us. However, the success of speedy hiring depends on how quickly you can prepare the documentation and sign the contract. We count the timing of recruitment only after all details are negotiated between 4IRE and the client, all vacancy requirements are negotiated, and the actual hiring process begins.

    Do your Solidity developers speak English well?

    Yes, 4IRE is a company with a solid international presence catering to clients’ needs across the globe. Thus, we emphasize the English proficiency of all our coders during the recruitment process. We check the command of English at preliminary candidate screening stages and hire coders with at least an Intermediate level of English knowledge. 

    Can I see the Solidity developer's CV?

    Yes, we provide all relevant candidates’ CVs for your review after the process of negotiating your project needs is over. 4IRE recruiters choose the most appropriate Solidity coders from our database to simplify your selection process.

    Where are your Solidity developers located?

    The company’s headquarters and main office, where in-house coders work, are located in Ukraine. Thus, most full-time Solidity developers employed at 4IRE operate from Ukrainian facilities. We also have a large remote team of Solidity engineers operating from different European locations.

    How much does it cost to hire Solidity developers?

    Solidity developers are a highly demanded category of blockchain engineers today, as they work with the primary programming language of Ethereum and other EVM-compatible blockchains. Given the rising demand for Solidity-powered projects, you should expect to pay $80-$100 for one hour of a Solidity coder’s work. Yet, the specific rates depend on your project’s complexity, the tech stack and seniority level of a particular developer, and the hiring model you choose. Feel free to discuss the rate for our dedicated Solidity coders with a 4IRE hiring manager. 

    How do I start?

    The first step you should take is to book a call with our representative. A 4IRE manager will call you to discuss the recruitment terms and your project needs. The more details about your project you share, the more equipped we’ll be to offer you the best dedicated team hiring terms and the most relevant Solidity experts.
